FIG. 1 may be essential parts and/or a number of components
included in the mobile terminal 100 may vary. Components of the
mobile terminal 100 may now be described.
[0059] The wireless communication unit 110 may include at least one
module that enables radio communication between the mobile terminal
100 and a radio communication system or between the mobile terminal
100 and a network in which the mobile terminal 100 is located. For
example, the wireless communication unit 110 may include a
broadcasting receiving module 111, a mobile communication module
112, a wireless Internet module 113, a short range communication
module 114 (or local area communication module), and a location
information module 115 (or position information module).
[0060] The broadcasting receiving module 111 may receive
broadcasting signals and/or broadcasting related information from
an external broadcasting management server through a broadcasting
channel. The broadcasting channel may include a satellite channel
and a terrestrial channel, and the broadcasting management server
may be a server that generates and transmits broadcasting signals
and/or broadcasting related information or a server that receives
previously created broadcasting signals and/or broadcasting related
information and transmits the broadcasting signals and/or
broadcasting related information to a terminal.
[0061] The broadcasting signals may include not only TV
broadcasting signals, radio broadcasting signals, and data
broadcasting signals but also signals in the form of a combination
of a TV broadcasting signal and a radio broadcasting signal. The
broadcasting related information may be information on a
broadcasting channel, a broadcasting program or a broadcasting
service provider, and may be provided even through a mobile
communication network. In the latter case, the broadcasting related
information may be received by the mobile communication module
112.
[0062] The broadcasting related information may exist in various
forms. For example, the broadcasting related information may exist
in the form of an electronic program guide (EPG) of a digital
multimedia broadcasting (DMB) system or in the form of an
electronic service guide (ESG) of a digital video
broadcast-handheld (DVB-H) system.
[0063] The broadcasting receiving module 111 may receive
broadcasting signals using various broadcasting systems. More
particularly, the broadcasting receiving module 111 may receive
digital broadcasting signals using digital broadcasting systems
such as a digital multimedia broadcasting-terrestrial (DMB-T)
system, a digital multimedia broadcasting-satellite (DMB-S) system,
a media forward link only (MediaFLO) system, a DVB-H and integrated
services digital broadcast-terrestrial (ISDB-T) systems. The
broadcasting receiving module 111 may receive signals from
broadcasting systems providing broadcasting signals other than the
above-described digital broadcasting systems.
[0064] The broadcasting signals and/or broadcasting related
information received through the broadcasting receiving module 111
may be stored in the memory 160. The mobile communication module
112 may transmit/receive a radio signal to/from at least one of a
base station, an external terminal and a server on a mobile
communication network. The radio signal may include a voice call
signal, a video telephony call signal or data in various forms
according to transmission and reception of text/multimedia
messages.
[0065] The wireless Internet module 113 may correspond to a module
for wireless Internet access and may be included in the mobile
terminal 100 or may be externally attached to the mobile terminal
100. Wireless LAN (WLAN or Wi-Fi), wireless broadband (Wibro),
world interoperability for microwave access (Wimax), high speed
downlink packet access (HSDPA) and so on may be used as a wireless
Internet technique.
[0066] The short range communication module 114 may correspond to a
module for short range communication. Further, Bluetooth.RTM.,
radio frequency identification (RFID), infrared data association
(IrDA), ultra wideband (UWB) and/or ZigBee.RTM. may be used as a
short range communication technique.
[0067] The location information module 115 may confirm or obtain a
location or a position of the mobile terminal 100. The location
information module 115 may obtain position information by using a
global navigation satellite system (GNSS). The GNSS is a
terminology describing a radio navigation satellite system that
revolves around the earth and transmits reference signals to
predetermined types of radio navigation receivers such that the
radio navigation receivers can determine their positions on the
earth's surface or near the earth's surface. The GNSS may include a
global positioning system (GPS) of the United States, Galileo of
Europe, a global orbiting navigational satellite system (GLONASS)
of Russia, COMPASS of China, and a quasi-zenith satellite system
(QZSS) of Japan, for example.
[0068] A global positioning system (GPS) module is a representative
example of the location information module 115. The GPS module may
calculate information on distances between one point or object and
at least three satellites and information on a time when distance
information is measured and apply trigonometry to the obtained
distance information to obtain three-dimensional position
information on the point or object according to latitude, longitude
and altitude at a predetermined time.
[0069] A method of calculating position and time information using
three satellites and correcting the calculated position and time
information using another satellite may also be used. Additionally,
the GPS module may continuously calculate a current position in
real time and calculate velocity information using the location or
position information.
[0070] The A/V input unit 120 may input (or receive) an audio
signal and/or a video signal. The A/V input unit 120 may include a
camera 121 and a microphone 122. The camera 121 may process image
frames of still images or moving images obtained by an image sensor
in a video telephony mode or a photographing mode. The processed
image frames may be displayed on a display 151, which may be a
touch screen.
[0071] The image frames processed by the camera 121 may be stored
in the memory 160 or may be transmitted to an external device
through the wireless communication unit 110. The mobile terminal
100 may also include at least two cameras 121.
[0072] The microphone 122 may receive an external audio signal in a
call mode, a recording mode and/or a speech recognition mode, and
the microphone 122 may process the received audio signal into
electric audio data. The audio data may then be converted into a
form that can be transmitted to a mobile communication base station
through the mobile communication module 112 and output in the call
mode. The microphone 122 may employ various noise removal
algorithms (or noise canceling algorithm) for removing or reducing
noise generated when the external audio signal is received.
[0073] The user input unit 130 may receive input data for
controlling operation of the mobile terminal 100 from a user. The
user input unit 130 may include a keypad, a dome switch, a touch
pad (constant voltage/capacitance), a jog wheel, a jog switch
and/or so on.
[0074] The sensing unit 140 may sense a current state of the mobile
terminal 100, such as an open/close state of the mobile terminal
100, a position of the mobile terminal 100, whether a user touches
the mobile terminal 100, a direction of the mobile terminal 100,
and acceleration/deceleration of the mobile terminal 100, and the
sensing unit 140 may generate a sensing signal for controlling
operation of the mobile terminal 100. For example, in an example of
a slide phone, the sensing unit 140 may sense whether the slide
phone is opened or closed. Further, the sensing unit 140 may sense
whether the power supply 190 supplies power and/or whether the
interface 170 is connected to an external device. The sensing unit
140 may also include a proximity sensor 141. The sensing unit 140
may sense a motion of the mobile terminal 100.
[0075] The output unit 150 may generate visual, auditory and/or
tactile output, and the output unit 150 may include the display
151, an audio output module 152, an alarm 153 and a haptic module
154. The display 151 may display information processed by the
mobile terminal 100. The display 151 may display a user interface
(UI) and/or a graphic user interface (GUI) related to a telephone
call when the mobile terminal 100 is in the call mode. The display
151 may also display a captured and/or received image, a UI or a
GUI when the mobile terminal 100 is in the video telephony mode or
the photographing mode.
[0076] The display 151 may include at least one of a liquid crystal
display, a thin film transistor liquid crystal display, an organic
light-emitting diode display, a flexible display and/or a
three-dimensional display. The display 151 may be of a transparent
type or a light transmissive type. That is, the display 151 may
include a transparent display.
[0077] The transparent display may be a transparent liquid crystal
display. A rear structure of the display 151 may also be of a light
transmissive type. Accordingly, a user may see an object located
behind the body (of the mobile terminal 100) through the
transparent area of the body of the mobile terminal 100 that is
occupied by the display 151.
[0078] The mobile terminal 100 may also include at least two
displays 151. For example, the mobile terminal 100 may include a
plurality of displays 151 that are arranged on a single face at a
predetermined distance or integrated displays. The plurality of
displays 151 may also be arranged on different sides.
[0079] When the display 151 and a sensor sensing touch (hereafter
referred to as a touch sensor) form a layered structure that is
referred to as a touch screen, the display 151 may be used as an
input device in addition to an output device. The touch sensor may
be in the form of a touch film, a touch sheet, and/or a touch pad,
for example.
[0080] The touch sensor may convert a variation in pressure applied
to a specific portion of the display 151 or a variation in
capacitance generated at a specific portion of the display 151 into
an electric input signal. The touch sensor may sense pressure of
touch as well as position and area of the touch.
[0081] When the user applies a touch input to the touch sensor, a
signal corresponding to the touch input may be transmitted to a
touch controller. The touch controller may then process the signal
and transmit data corresponding to the processed signal to the
controller 180. Accordingly, the controller 180 may detect a
touched portion of the display 151.
[0082] The proximity sensor 141 (of the sensing unit 140) may be
located in an internal region of the mobile terminal 100,
surrounded by the touch screen, and/or near the touch screen. The
proximity sensor 141 may sense an object approaching a
predetermined sensing face or an object located near the proximity
sensor 141 using an electromagnetic force or infrared rays without
having mechanical contact. The proximity sensor 141 may have a
lifetime longer than a contact sensor and may thus have a wide
application in the mobile terminal 100.
[0083] The proximity sensor 141 may include a transmission type
photo-electric sensor, a direct reflection type photo-electric
sensor, a mirror reflection type photo-electric sensor, a
high-frequency oscillating proximity sensor, a capacitive proximity
sensor, a magnetic proximity sensor, and/or an infrared proximity
sensor. A capacitive touch screen may be constructed such that
proximity of a pointer is detected through a variation in an
electric field according to the proximity of the pointer. The touch
screen (touch sensor) may be classified as a proximity sensor
141.
[0084] For ease of explanation, an action of the pointer
approaching the touch screen without actually touching the touch
screen may be referred to as a proximity touch and an action of
bringing the pointer into contact with the touch screen may be
referred to as a contact touch. The proximity touch point of the
pointer on the touch screen may correspond to a point of the touch
screen at which the pointer is perpendicular to the touch
screen.
[0085] The proximity sensor 141 may sense the proximity touch and a
proximity touch pattern (e.g., a proximity touch distance, a
proximity touch direction, a proximity touch velocity, a proximity
touch time, a proximity touch position, a proximity touch moving
state, etc.). Information corresponding to the sensed proximity
touch action and proximity touch pattern may then be displayed on
the touch screen.
[0086] The audio output module 152 may output audio data received
from the wireless communication unit 110 or stored in the memory
160 in a call signal receiving mode, a telephone call mode or a
recording mode, a speech recognition mode and a broadcasting
receiving mode. The audio output module 152 may output audio
signals related to functions, such as a call signal incoming tone
and a message incoming tone, performed in the mobile terminal 100.
The audio output module 152 may include a receiver, a speaker, a
buzzer, and/or the like. The audio output module 152 may output
sounds through an earphone jack. The user may hear the sounds by
connecting an earphone to the earphone jack.
[0087] The alarm 153 may output a signal for indicating generation
of an event of the mobile terminal 100. For example, an alarm may
be generated when receiving a call signal, receiving a message,
inputting a key signal, and/or inputting a touch. The alarm 153 may
also output signals in forms different from video signals or audio
signals, for example, a signal for indicating generation of an
event through vibration. The video signals and/or the audio signals
may also be output through the display 151 or the audio output
module 152.
[0088] The haptic module 154 may generate various haptic effects
that the user can feel. One example of the haptic effects is
vibration. An intensity and/or pattern of vibration generated by
the haptic module 154 may also be controlled. For example,
different vibrations may be combined and output or may be
sequentially output.
[0089] The haptic module 154 may generate a variety of haptic
effects including an effect of stimulus according to an arrangement
of pins vertically moving against a contact skin surface, an effect
of stimulus according to a jet force or sucking force of air
through a jet hole or a sucking hole, an effect of stimulus of
rubbing the skin, an effect of stimulus according to contact of an
electrode, an effect of stimulus using an electrostatic force, and
an effect according to a reproduction of cold and warmth using an
element capable of absorbing or radiating heat in addition to
vibrations.
[0090] The haptic module 154 may not only transmit haptic effects
through direct contact but may also allow the user to feel haptic
effects through a kinesthetic sense of the user's fingers or arms.
The mobile terminal 100 may also include a plurality of haptic
modules 154.
[0091] The memory 160 may store a program for operations of the
controller 180 and/or temporarily store input/output data such as a
phone book, messages, still images, and/or moving images. The
memory 160 may also store data about vibrations and sounds in
various patterns that are output from when a touch input is applied
to the touch screen.
[0092] The memory 160 may include at least a flash memory, a hard
disk type memory, a multimedia card micro type memory, a card type
memory, such as SD or XD memory, a random access memory (RAM), a
static RAM (SRAM), a read-only memory (ROM), an electrically
erasable programmable ROM (EEPROM), a programmable ROM (PROM)
magnetic memory, a magnetic disk and/or an optical disk. The mobile
terminal 100 may also operate in relation to a web storage that
performs a storing function of the memory 160 on the Internet.
[0093] The interface 170 may serve as a path to external devices
connected to the mobile terminal 100. The interface 170 may receive
data from the external devices or power and transmit the data or
power to internal components of the mobile terminal 100 or transmit
data of the mobile terminal 100 to the external devices. For
example, the interface 170 may include a wired/wireless headset
port, an external charger port, a wired/wireless data port, a
memory card port, a port for connecting a device having a user
identification module, an audio I/O port, a video I/O port, and/or
an earphone port.
[0094] The interface 170 may also interface with a user
identification module that is a chip that stores information for
authenticating authority to use the mobile terminal 100. For
example, the user identification module may be a user identity
module (UIM), a subscriber identity module (SIM) and/or a universal
subscriber identity module (USIM). An identification device
(including the user identification module) may also be manufactured
in the form of a smart card. Accordingly, the identification device
may be connected to the mobile terminal 100 through a port of the
interface 170.
[0095] The interface 170 may also be a path through which power
from an external cradle is provided to the mobile terminal 100 when
the mobile terminal 100 is connected to the external cradle or a
path through which various command signals input by the user
through the cradle are transmitted to the mobile terminal 100. The
various command signals or power input from the cradle may be used
as signals for confirming whether the mobile terminal 100 is
correctly set in the cradle.
[0096] The controller 180 may control overall operations of the
mobile terminal 100. For example, the controller 180 may perform
control and processing for voice communication, data communication
and/or video telephony. The controller 180 may also include a
multimedia module 181 for playing multimedia. The multimedia module
181 may be included in the controller 180 or may be separated from
the controller 180.
[0097] The controller 180 may perform a pattern recognition process
capable of recognizing handwriting input or picture-drawing input
applied to the touch screen as characters or images. The power
supply 190 may receive external power and internal power and
provide power required for operations of the components of the
mobile terminal 100 under control of the controller 180.
[0098] According to hardware implementation, embodiments may be
implemented using at least one of application specific integrated
circuits (ASICs), digital signal processors (DSPs), digital signal
processing devices (DSPDs), programmable logic devices (PLDs),
field programmable gate arrays (FPGAs), processors, controllers,
micro-controllers, microprocessors, and/or electrical units for
executing functions. Embodiments may be implemented by the
controller 180.
[0099] According to software implementation, embodiments such as
procedures or functions may be implemented with a separate software
module that executes at least one function or operation. Software
codes may be implemented according to a software application
written in an appropriate software language. The software codes may
be stored in the memory 160 and executed by the controller 180.
[0100] FIG. 2A is a front perspective view of a mobile terminal (or
a handheld terminal) according to an embodiment.
[0101] The mobile terminal 100 may be a bar type terminal body.
However, embodiments are not limited to a bar type terminal and may
be applied to terminals of various types including slide type,
folder type, swing type and/or swivel type terminals having at
least two bodies that are relatively movably combined.
[0102] The terminal body may include a casing (or a housing or a
cover) that forms an exterior of the mobile terminal 100. In this
embodiment, the casing may be divided into a front casing 101 and a
rear casing 102. Various electronic components may be arranged in
the space formed between the front casing 101 and the rear casing
102. At least one middle casing may be additionally provided
between the front casing 101 and the rear casing 102.
[0103] The casings may be formed of plastics through injection
molding or made of a metal material such as stainless steel (STS)
or titanium (Ti).
[0104] The display 151, the audio output unit 152, the camera 121,
the user input unit 130/131 and 132, the microphone 122 and the
interface 170 may be arranged (or provided) in the terminal body,
and more specifically may be arranged (or provided) in the front
casing 101.
[0105] The display 151 may occupy most of the main face of the
front casing 101. The audio output unit 152 and the camera 121 may
be arranged in a region in proximity to one of both ends of the
display 151 and the user input unit 131, and the microphone 122 may
be located in a region in proximity to another end of the display
151. The user input unit 132 and the interface 170 may be arranged
(or provided) on sides of the front casing 101 and the rear casing
102.
[0106] The user input unit 130 may receive commands for controlling
operation of the mobile terminal 100, and may include a plurality
of operating units 131 and 132. The operating units 131 and 132 may
be referred to as manipulating portions and may employ any tactile
manner in which a user operates the operating units 131 and 132
while having tactile feeling.
[0107] The first and second operating units 131 and 132 may receive
various inputs. For example, the first operating unit 131 may
receive commands such as start, end and scroll and the second
operating unit 132 may receive commands such as control of a volume
of sound output from the audio output unit 152 or conversion of the
display 151 to a touch recognition mode.
[0108] FIG. 2B is a rear perspective view of the mobile terminal
(shown in FIG. 2A) according to an embodiment.
[0109] Referring to FIG. 2A, a camera 121' may be additionally
attached to the rear side of the terminal body (i.e., the rear
casing 102). The camera 121' may have a photographing direction
opposite to that of the camera 121 (shown in FIG. 2A) and may have
pixels different from those of the camera 121 (shown in FIG.
2A).
[0110] For example, it may be desirable that the camera 121 has low
pixels such that the camera 121 may capture an image of a face of a
user and transmit the image to a receiving part in case of video
telephony while the camera 121' has high pixels because the camera
121' captures an image of a general object and does not immediately
transmit the image in many cases. The cameras 121 and 121' may be
attached (or provided) to the terminal body such that the cameras
121 and 121' may rotate or pop-up.
[0111] A flash bulb 123 and a mirror 124 may be additionally
provided in proximity to the camera 121'. The flash bulb 123 may
light an object when the camera 121' takes a picture of the object.
The mirror 124 may be used for the user to look at his/her face in
the mirror when the user wants to self-photograph himself/herself
using the camera 121'.
[0112] An audio output unit 152' may be additionally provided on
the rear side of the terminal body. The audio output unit 152' may
achieve a stereo function with the audio output unit 152 (shown in
FIG. 2A) and may be used for a speaker phone mode when the terminal
is used for a telephone call.
[0113] A broadcasting signal receiving antenna may be additionally
attached (or provided) to the side of the terminal body in addition
to an antenna for telephone calls. The antenna constructing a part
of the broadcasting receiving module 111 (shown in FIG. 1) may be
set in the terminal body such that the antenna may be pulled out of
the terminal body.
[0114] The power supply 190 for providing power to the mobile
terminal 100 may be set in the terminal body. The power supply 190
may be included in the terminal body or may be detachably attached
to the terminal body.
[0115] A touch pad 135 for sensing touch may be attached to the
rear casing 102. The touch pad 135 may be of a light transmission
type, such as the display 151. In this example, if the display 151
outputs visual information through both sides thereof, the visual
information may be recognized (or determined) by the touch pad 135.
The information output through both sides of the display 151 may be
controlled by the touch pad 135. Otherwise, an additional display
may be attached (or provided) to the touch pad 135 such that a
touch screen is arranged (or provided) even in the rear casing
102.
[0116] The touch pad 135 may operate in connection with the display
151 of the front casing 101. The touch pad 135 may be located in
parallel with the display 151 behind the display 151. The touch
panel 135 may be identical to or smaller than the display 151 in
size.
[0117] FIGS. 2C and 2D illustrate the mobile terminal 100 and the
display 151 according to various embodiments.
[0118] Referring to FIG. 2C, the display 151 may include a first
display and a second display that are physically separated from
each other. In a folder type or slide type mobile terminal having
two bodies connected through a hinge or a slide, the first display
(or main display) may be formed on the inner face or outer face of
one of the bodies, and the second display (or sub display) may be
formed on the inner face or outer face of the other body. The sub
display may be separated from the mobile terminal and may be
detachably combined with the mobile terminal body through an
interface to display data from the mobile terminal 100.
[0119] The display 151 may include first and second displays that
may be logically separated from each other in a display panel, as
shown in FIG. 2D.
[0120] FIG. 3 is a view for explaining a proximity depth of a
proximity sensor.
[0121] As shown in FIG. 3, when a pointer (such as a user's finger)
approaches the touch screen, the proximity sensor located inside or
near the touch screen may sense the approach of the pointer, and
may output a proximity signal.
[0122] The proximity sensor may be constructed such that the
proximity sensor outputs a proximity signal according to a distance
between the pointer approaching the touch screen and the touch
screen (referred to as "proximity depth").
[0123] The distance in which the proximity signal is output when
the pointer approaches the touch screen may be referred to as a
detection distance. The proximity depth may be determined by using
a plurality of proximity sensors having different detection
distances and by comparing proximity signals respectively output
from the proximity sensors.
[0124] FIG. 3 shows a section of the touch screen in which
proximity sensors capable of sensing three proximity depths may be
provided. Proximity sensors capable of sensing less than three or
more than four proximity depths may be provided in the touch
screen.
[0125] More specifically, when the pointer completely contacts the
touch screen (D0), it may be recognized as contact touch. When the
pointer is located within a distance D1 from the touch screen, it
may be recognized as a proximity touch of a first proximity depth.
When the pointer is located in a range between the distance D1 and
a distance D2 from the touch screen, it may be recognized as a
proximity touch of a second proximity depth. When the pointer is
located in a range between the distance D2 and a distance D3 from
the touch screen, it may be recognized as a proximity touch of a
third proximity depth. When the pointer is located greater than the
distance D3 from the touch screen, it may be recognized as
cancellation of the proximity touch.
[0126] Accordingly, the controller 180 may recognize the proximity
touch as various input signals according to proximity distance and
proximity position of the pointer with respect to the touch screen,
and the controller 810 may perform various operation controls
according to the input signals.
[0127] Referring to FIG. 4, a CDMA wireless communication system
includes mobile terminals 100, base stations 270, base station
controllers 275, and a mobile switching center 280. The mobile
switching center 280 is connected to a public switch telephone
network (PSTN) 290. The mobile switching center 280 is connected to
the base station controllers 275. The base station controllers 275
are connected to the base stations 270 through backhaul lines. The
backhaul lines may be constructed according to E1/T1, ATM, IP, PPP,
frame relay, HDSL, ADSL or xDSL well-known in the art. The CDMA
wireless communication system may include at least two base station
controllers 275.
[0128] Each base station 270 may include a sector or sectors and
each sector may include an omnidirectional antenna or an antenna
adjusted to a specific radiation direction from the base station
270. Otherwise, each sector may include two diversity reception
antennas. Each base station 270 is constructed to have frequency
assignments, and the frequency assignments may have specific
spectra (for example, 1.25 MHz and 5 MHz).
[0129] Intersection of sectors and frequency assignments may be
referred to a CDMA channel.
[0130] The base stations 270 may be referred to as base station
transceiver subsystems (BTSs). "Base station" may be used as a term
that collectively designates the base station controller 275 and
one or more base stations 270 in several examples. Furthermore, the
base stations 270 may be referred to as "cell sites". Otherwise,
individual sectors of a given base station 270 may be referred to
as cell sites.
[0131] A terrestrial DMB transmitter 295 can transmit broadcasting
signals to the mobile terminals 100 operating in the CDMA wireless
communication system. The broadcasting receiving module 111 of each
mobile terminal 100 is constructed to receive the broadcasting
signals transmitted from the DMB transmitter 295. This can be
similarly applied to different types of broadcast and multicast
signaling as described above.
[0132] FIG. 4 illustrates global positioning system (GPS)
satellites 300. These satellites 300 can track the positions of
some or all of the mobile terminals 100. Although two satellites
are shown in FIG. 4, position information can be obtained from less
than or more than two satellites. In addition, other
position-tracking techniques (for example, position-tracking
techniques that can substitute for GPS technique or can be added to
the GPS technique) can be used. If required, some or all of the GPS
satellites 300 can support satellite DMB transmission separately or
additionally.
[0133] When the CDMA wireless communication system operates, the
base stations 270 receive reverse link signals from the mobile
terminals 100. The mobile terminals 100 may be in a state that the
mobile terminals 100 are making calls, sending messages or
performing other communications. The reverse link signals received
by the base stations 270 are processed by the base stations 270.
The processed data is transmitted to the base station controllers
275 connected to the base stations 270. The base station
controllers 275 provide call resource allocation and mobility
management functionality including soft handoffs between the base
stations 270. Furthermore, the base station controllers 275
transmit the received data to the mobile switching center 280. The
mobile switching center 280 provides additional routing services
for interfacing with the PSTN 290. Similarly, the PSTN 290
interfaces with the mobile switching center 280, and the mobile
switching center 280 interfaces with the base station controllers
275. The base station controllers 275 control the base stations 270
to transmit forward link signals to the mobile terminals 100.
[0134] FIG. 5A is a flowchart illustrating a method of controlling
the mobile terminal in accordance with an embodiment of the present
invention.
[0135] As shown in FIG. 5A, the mobile terminal 100 in accordance
with an embodiment of the present invention can convert at least
one selection region of a ring-shaped image, captured by a first
camera 200 (see FIG. 36) for performing omnidirectional
photographing, into a rectangular image and display the rectangular
image on the display 151.
[0136] The first camera (i.e., a small-sized omnidirectional
camera) 200 embedded in the mobile terminal 100 can perform
360-degree (i.e., omnidirectional) photographing at step S101.
[0137] The mobile terminal 100 can include the omnidirectional
camera 200 on one side thereof. The lens of the omnidirectional
camera 200 can capture an image through a field of view of 360
degrees. That is, the lens of the omnidirectional camera 200 can be
a spherical lens.
[0138] The rear camera 121' can be provided in the rear of the
mobile terminal 100. The rear camera 121' can perform
one-directional photographing. That is, the lens of the rear camera
121' can capture an image through a field of view of approximately
65 degrees.
[0139] The omnidirectional camera 200 and the rear camera (i.e.,
one-directional camera) 121' can operate at the same time. The
photographing screen of the omnidirectional camera and the
photographing screen of the one-directional camera can be displayed
in a display. A photographing direction of the omnidirectional
camera 200 may be identical with that of the one-directional camera
121'.
[0140] The controller 180 can display an indicator indicative of a
standard direction for photographing. The controller 180 can
control a standard direction for photographing.
[0141] In response to a specific event generated while the
omnidirectional camera 200 operates, the controller 180 can operate
the one-directional camera 121'.
[0142] While the one-directional camera 121' operates, the
controller 180 can automatically store an image having a field of
view of 360 degrees through the omnidirectional camera 200. The
controller 180 can display the photographing screen of the
omnidirectional camera 200 on the display 151.
[0143] The controller 180 can convert a captured ring-shaped image
into a rectangular image at step S103.
[0144] An image captured by the omnidirectional camera 200 is a
ring-shaped image. That is, the controller 180 can obtain a
ring-shaped image having a doughnut shape. The controller 180 can
convert the captured ring-shaped image into the rectangular image.
That is, the controller 180 can convert the captured ring-shaped
image having a doughnut shape into a form in which the ring-shaped
image is spread on the basis of one region of the ring-shaped
image, that is, a rectangular image.
[0145] The controller 180 can display the rectangular image on the
display 151 at step S105.
[0146] The controller 180 can correct the distortion of objects
included in the rectangular image and display a corrected image.
The controller 180 can perform edition on part of the rectangular
image, such as enlargement, reduction, and partitioning, and
display an edited image.
[0147] The controller 180 can display an image having a field of
view of 360 degrees on the display 151 in a drum form. That is, the
controller 180 can display a 360-degree captured image so that it
is intuitively recognized.
[0148] FIG. 5B is a diagram showing an image captured by the
omnidirectional camera 200 in accordance with an embodiment of the
present invention.
[0149] As shown FIG. 5B, the mobile terminal 100 including the
omnidirectional camera 200 in accordance with an embodiment of the
present invention can capture an image having a field of view of
360 degrees around the mobile terminal.
[0150] As shown in (a) of FIG. 5B, the controller 180 can capture
an image having a field of view of 360 degrees around the mobile
terminal 100. R1 is illustrated as being an image captured by the
lens of the omnidirectional camera in order to help intuitive
understanding.
[0151] As shown in (b) of FIG. 5B, an image captured by the
omnidirectional camera can be a ring-shaped image. The ring-shaped
image captured by the omnidirectional camera may be partially
distorted as compared with an image actually recognized through a
field of view. That is, it means that an image captured by a
spherical lens may be distorted when the image is displayed on a
plane.
[0152] An image of a user 11 located at a relatively close distance
from the mobile terminal 100 may occupy a relatively larger portion
than other objects included in the ring-shaped image.
[0153] As shown in (c) of FIG. 5B, the ring-shaped image can be
converted into a rectangular image and displayed on the display
151. That is, the controller 180 can convert the ring-shaped image
having a doughnut shape into the rectangular image by spreading the
ring-shaped image on the basis of any one portion thereof.
[0154] The rectangular image can include a 360-degree image around
the mobile terminal 100. That is, scenes corresponding to the
locations of 90 degrees, 180 degrees, and 270 degrees at specific
intervals on the basis of one end (0 degree) of the rectangular
image can be seen.
[0155] When an image is captured by the omnidirectional camera 200,
an omnidirectional still or moving image can be captured. That is,
if it is sought to capture an image around a specific target, the
mobile terminal 100 does not change its photographing direction
although the specific target moves.
[0156] Furthermore, the mobile terminal 100 can capture an image,
including a specific target, and surrounding situations. That is,
the mobile terminal 100 can obtain pieces of information about
temperature, humidity, and locations, including a visual image that
can be captured by the lens of the omnidirectional camera. For
example, the mobile terminal 100 can store temperature, humidity,
etc. obtained by sensors included in the mobile terminal along with
a captured visual image. Furthermore, the mobile terminal 100 can
obtain information about a location using a GPS (the location
information module 115 of FIG. 1) and store the obtained
information.
[0157] When photographing is performed by a camera capable of
one-directional photographing in the form of a panorama shot, a
missing part may occur between a first shot and a second shot. In
accordance with an embodiment of the present invention, when
photographing is performed by the omnidirectional camera 200,
omnidirectional and simultaneous photographing can be performed
even without switching the direction of the mobile terminal
100.
[0158] FIG. 6 is a diagram showing an image in which the distortion
of objects has been corrected in accordance with an embodiment of
the present invention.
[0159] As shown FIG. 6, an image captured by the omnidirectional
camera 200 may include distorted objects.
[0160] FIG. 6(a) is a diagram showing a rectangular image including
distorted objects. That is, an image captured by a spherical lens
may be distorted when the image is displayed on a plane.
[0161] As shown in FIG. 6(b), the controller 180 can correct the
distorted objects included in the rectangular image and display an
image including the corrected objects so that the image including
the corrected objects is close to an image that is actually
recognized by a user through a field of view.
[0162] The controller 180 can control the degree of correction for
a captured image by applying a specific correction algorithm to the
captured image. That is, the controller 180 can mitigate the degree
of the distortion of objects and display an image having the
mitigated degree of distortion. Furthermore, the controller 180 can
deepen the degree of the distortion of objects and display an image
having the deepened degree of distortion. Furthermore, the
controller 180 can display a captured image as it is without
applying a correction algorithm to the captured image.
[0163] FIG. 7 is a diagram showing an image captured by the
omnidirectional camera 200 in accordance with an embodiment of the
present invention.
[0164] As shown in FIG. 7, a user 12 can perform 360-degree
photographing around the mobile terminal 100.
[0165] I1 is an image captured by the omnidirectional camera 200
and displayed in a cylindrical form so that the image can be
intuitively recognized. I1 can include a shape of the user 12
located in a self-shot direction.
[0166] A 360-degree image captured by the omnidirectional camera
200 is hereinafter illustrated in a cylindrical form so that the
360-degree image can be intuitively recognized. Furthermore, in
order to help understanding, objects included in an image displayed
in a cylindrical form have been corrected, and thus the image can
be displayed so that it is close to an image actually recognized
through a field of view.
[0167] FIG. 8 is a diagram showing the display 151 in which an
image captured by the omnidirectional camera 200 is displayed in
accordance with an embodiment of the present invention.
[0168] As shown in FIG. 8(a), the omnidirectional camera 200 can
capture an omnidirectional image I2 around the mobile terminal 100.
When the omnidirectional image I2 is captured, the controller 180
may use a specific direction in the omnidirectional image, for
example, an arrow direction indicated in the omnidirectional image
I2 as a standard.
[0169] The controller 180 can convert at least one region of a
ring-shaped image, captured by the omnidirectional camera 201, into
a rectangular image and display the rectangular image on the
display 151.
[0170] As shown in FIG. 8(b), the controller 180 can display an
image corresponding to a specific direction in the captured image
I2, that is, an image corresponding to a standard direction, on the
display 151. That is, one region A1 of the entire image I2, that
is, a 360-degree image, can be displayed on the display 151. For
example, if an image is captured based on the arrow direction of
FIG. 8(a), the controller 180 can display a portion of the captured
image, including a user 13, on the display 151 by default.
[0171] As shown in FIG. 8(c), the controller 180 can enlarge the
one region A1 corresponding to the standard direction, in the
entire image A2, and display an image including the enlarged region
A1. Furthermore, the controller 180 can display the entire
360-degree image A2 on the display 151.
[0172] The controller 180 can convert a ring-shaped image, captured
by the omnidirectional camera 200, into a rectangular image and
display the rectangular image on the display 151. The controller
180 may store the ring-shaped image in the memory 160, convert the
stored ring-shaped image into the rectangular image, and display
the converted ring-shaped image on the display 151. In one
embodiment, before storing the ring-shaped image, the controller
180 may convert the ring-shaped image into the rectangular image
and display the converted rectangular image on the display 151. A
user can intuitively check an omnidirectional image on the display
151 simultaneously with the capturing of the omnidirectional
image.
[0173] FIGS. 9 to 11 are diagrams showing an example of the display
151 when the omnidirectional camera and the one-directional camera
operate.
[0174] The mobile terminal 100 can include the first camera 200 for
performing omnidirectional photographing and a second camera for
performing photographing in a specific direction. The controller
180 can control at least one of the first camera and the second
camera so that the mobile terminal 100 operates in any one of a
first mode in which the first camera operates and a second mode in
which both the first camera and the second camera operate.
[0175] As shown in FIG. 9(a), the controller 180 can display an
image A4 capable of being captured by the first camera 200 and an
image A3 capable of being captured by the second camera on the
display 151.
[0176] In an embodiment, the controller 180 can perform control so
that the image A3 occupies the entire display 151 in response to a
signal generated by upward dragging the image A3 through a finger
F1 or the like, such as touch & drag. As a result, as shown in
FIG. 9(b), only the image A3 capable of being captured by the
second camera can be displayed on the display 151. That is, the
controller 180 can drive the second camera only.
[0177] FIG. 10(a) is a diagram showing the display 151 in which the
second camera for performing photographing in a specific direction
operates. The second camera for performing photographing in a
specific direction can be a camera capable of photographing within
a range of a field of view of, for example, 65 degrees around the
lens of the second camera. The controller 180 can display an image
having a field of view of 65 degrees on the display 151.
[0178] At this time, the controller 180 can also drive the first
camera 200 for performing omnidirectional photographing. As shown
in FIG. 10(b), the controller 180 can display a captured 360-degree
image in response to a signal generated by downward dragging the
upper end of the display 151 through a finger F3 or the like.
[0179] While driving the second camera, the controller 180 can
store surrounding situations automatically. The surrounding
situations can include an image capable of being captured by the
omnidirectional camera and pieces of information about temperature,
humidity, and a location.
[0180] As shown in FIG. 11(a), the first camera and the second
camera can operate at the same time. The controller 180 can display
a first image A8 capable of being captured by the first camera on
the display 151. The controller 180 can display a second image A7
capable of being captured by the second camera on the display
151.
[0181] The controller 180 can display an indicator m1, indicating
the location of a region corresponding to the second image A7
captured by the second camera, in the first image A8 captured by
the first camera. For example, as shown in FIG. 11(a), the
controller 180 can display the indicator m1 at the location of a
region corresponding to a region in which t1 captured by the second
camera is located.
[0182] As shown in FIG. 11(b), when t2 is captured by the second
camera, the controller 180 can display an indicator m2 at a
location of a first image A10 corresponding to a second image A9,
that is, a location where t2 is placed.
[0183] A user can change a photographing direction of the second
camera along portions to be photographed by the second camera while
checking the images A8 and A10 captured by the first camera. A user
can intuitively recognize a portion now being photographed by the
second camera by moving the indicator m2.
[0184] FIG. 12 is a diagram showing an example in which the
one-directional camera operates while the omnidirectional camera
operates.
[0185] As shown in FIG. 12, when a person, from among objects
included in an image, is captured while the omnidirectional camera
(i.e., the first camera) operates, the controller 180 can drive the
one-directional camera (i.e., the second camera).
[0186] As shown in FIG. 12(a), the controller 180 can display an
image A12 captured by the omnidirectional camera (i.e., the first
camera). The controller 180 can enlarge a portion of the image A12
corresponding to a standard direction and display the enlarged
portion A11 on the display 151.
[0187] As shown in FIG. 12(b), while a still or moving image is
captured, the controller 180 can capture a person 15 from among
objects included in the image (A13 and A14)
[0188] At this time, the controller 180 can drive the
one-directional camera (i.e., the second camera) capable of image
capturing having high-picture quality. The controller 180 can drive
the second camera and display an image A15 captured by the second
camera on the display 151.
[0189] FIG. 12 illustrates an example in which a camera is driven
when a person is captured while the camera captures an image. In
some embodiments, the controller 180 may drive the camera in
response to a predetermined event.
[0190] FIGS. 13 and 14 are diagrams showing an example of the
display 151 in which an image is edited and displayed.
[0191] The controller 180 can edit at least part of a rectangular
image so that the at least part corresponds to a display region of
the display 151 by using at least one of enlargement edition,
reduction edition, and partition edition methods.
[0192] As shown in FIG. 13, the controller 180 can enlarge one
region A18 of a captured image A17 and display the enlarged region
A1 on the display 151.
[0193] The controller 180 can display an indicator indicating the
location of at least some region of a rectangular image that is
being displayed on the display 180. That is, the controller 180 can
display an indicator m5 indicating the location of a portion that
is being displayed on the display 151, as shown in FIG. 13(b).
[0194] FIG. 13 is a diagram showing an example in which the mobile
terminal 100 is horizontally placed, and FIG. 14 is a diagram
showing an example in which the mobile terminal 100 is vertically
placed. As shown in FIG. 14, the controller 180 can enlarge some
region A20 of the entire image A19 and display the enlarged region
A20 on the display 151.
[0195] The controller 180 can display an indicator m6 indicating
that a portion now being displayed on the display 151 corresponds
to what region of the entire image A19 so that a user can
intuitively recognize the displayed portion.
[0196] FIGS. 15 and 16 are diagrams showing an example in which an
indicator indicative of the location of an image being displayed on
the display 151 is displayed.
[0197] As shown in FIG. 15(a), the controller 180 can perform
photographing based on a user direction d1, that is, a self-shot
direction d1. That is, the controller 180 can capture a 360-degree
image I5 based on the d1 direction through the omnidirectional
camera (i.e., the first camera).
[0198] As shown in FIG. 15(b), the controller 180 can display some
region of the entire image I5, that is, a region corresponding to
the standard direction d1 on the display 151. The controller 180
can display an indicator m7 so that a user can intuitively
recognize the direction of an image being displayed on the display
151. For example, the controller 180 can display a downward arrow
within a circular indicator m7 so that a user can intuitively
recognize that a self-shot direction is a standard direction.
[0199] The indicator can be displayed in various forms, such as a
circle, a bar (-) shape, a compass shape, a direction indication (4
shape, and a drum shape.
[0200] As shown in FIG. 16, the controller 180 can display some
regions A21 and A22 of the entire image on the display 151.
[0201] FIG. 16(b) shows an example in which the controller 180
displays the region A21 on the display 151. The controller 180 can
indicate an indicator m8 on the display 151 so that a user can
intuitively recognize the direction of the region A21 of the entire
image. For example, the controller 180 can display a downward arrow
d3 within a circular indicator m8 so that a user can intuitively
recognize an image in a self-shot direction.
[0202] As shown in FIG. 16(c), the controller 180 can display an
image A22 in the other direction in response to a signal generated
by a touch input to one direction of the circular indicator m8
through a finger F5 or the like. That is, when an input signal to
an upward direction d5 within the circular indicator m8 is
received, the controller 180 can display the image A22 in the front
direction of the mobile terminal 100, that is, a direction opposite
to the self-shot direction, on the display 151.
[0203] FIGS. 17 to 19 are diagrams showing an example in which the
location of an image being displayed on the display 151 is
changed.
[0204] As shown in FIG. 17, the controller 180 of the mobile
terminal 100 in accordance with an embodiment of the present
invention can display part of a captured omnidirectional image I7
on the display 151.
[0205] The controller 180 can display an indicator m9 indicating
the location of a region that is being displayed on the display
151. The controller 180 can change the location of an image being
displayed on the display 151, in response to a signal generated by
touching the location indication bar of the indicator m9 through a
finger F6 or the like. That is, the controller 180 can move the
location of the image I7, being displayed on the display 151, left
and right in response to a movement of the location indication bar
of the indicator m9 having a straight-line shape.
[0206] Accordingly, a user can intuitively check the location of a
portion of the entire image I7 being displayed on the display 151,
through the indicator m9.
[0207] As shown in FIG. 18, in another embodiment, the controller
180 can move the location of an image being displayed on the
display 151 in response to a signal that moves a circular indicator
m10 in a clockwise direction d7 through a finger F7 or the like.
Furthermore, in response to a signal that moves the circular
indicator m10 in a counterclockwise direction through a finger or
the like, the controller 180 can move the location of an image
being displayed on the display 151.
[0208] In yet another embodiment, the controller 180 can move the
location of an image being displayed on the display 151, in
response to a signal, such as a touch & drag signal, for an
image being displayed on the display 151 through a finger or the
like.
[0209] In yet another embodiment, the controller 180 can move the
location of an image being displayed on the display 151 in response
to an input signal generated through an additional button provided
in one region of the display 151 or a button provided outside the
mobile terminal 100.
[0210] In yet another embodiment, the mobile terminal 100 can
change the location of an image being displayed on the display 151
in response to a signal that moves the mobile terminal 100 left and
right, as shown in FIG. 19. That is, a displayed image A25 can be
moved in response to a movement of the mobile terminal 100.
[0211] FIG. 20 is a diagram showing an example in which a plurality
of partitioned images is displayed on the display 151.
[0212] As shown in FIG. 20, the controller 180 of the mobile
terminal 100 in accordance with an embodiment of the present
invention can partition an omnidirectional image into a plurality
of images and display the plurality of partitioned images on the
display 151 at the same time.
[0213] For example, the controller 180 can partition an image into
two images on the basis of 180 degrees. For example, the controller
180 can partition the display 151 into two regions A27 and A28. The
controller 180 can display the two partitioned images in the two
regions, respectively, at the same time. Accordingly, if an image
is a moving image, a user can view another image in another
direction in the same time zone at the same time.
[0214] The controller 180 can display images in different
directions in the partitioned regions A27 and A28. The controller
180 can display indicators m11 and m12, indicating the directions
of the respective partitioned images, in the respective regions A27
and A28. A direction d8 indicated by the indicator m11 displayed in
the region A27 is a front direction seen by a user, and a direction
d9 indicated by an indicator m12 displayed in the region A28 is the
self-shot direction of a user.
[0215] If an image is a moving image, the controller 180 can obtain
signals, such as play and a stop, through play buttons w1 and
w2.
[0216] FIGS. 21 to 23 are diagrams showing an example in which a
plurality of partitioned moving images is displayed on the display
151.
[0217] As shown, the controller 180 of the mobile terminal 100 in
accordance with an embodiment of the present invention can play and
stop a plurality of partitioned moving images.
[0218] As shown in FIG. 21(a), the controller 180 can display an
image in a direction d10 in a region A29 and an image in a
direction d11 in a region A30. If an image is a moving image, the
controller 180 can play images in different directions at the same
time. Play bars w3 and w4 can indicate locations of the entire
moving images that are now being played.
[0219] As shown in FIG. 21(b), the controller 180 can change a play
location in response to an input signal received through the play
bar w3. That is, the controller 180 can change a play location of
the image in the region A29 in the state in which the image in the
region A30 has been stopped.
[0220] Accordingly, a user can play a moving image in a desired
direction, of the entire image. Furthermore, a user can change a
time zone according to a desired time zone and play a moving image
in the desired time zone.
[0221] As shown in FIG. 22, the controller 180 of the mobile
terminal 100 in accordance with an embodiment of the present
invention can synchronize moving images in different directions in
the same time zone when playing the moving images.
[0222] As shown in FIG. 22(a), the controller 180 can play moving
images having different time zones in respective partitioned
regions A31 and A32. Play bars w6 and w7 indicate locations that
are being played, of the entire moving images.
[0223] The controller 180 can make a play location of the region
A32 identical with a play location of the region A31 in response to
a signal generated by touching a synchronization button b1
displayed in the region A31 through a finger F9 or the like.
[0224] In another embodiment, the controller 180 can make a play
location of the region A32 identical with a play location of the
region A31 in response to a signal generated by touching a
synchronization button b2 displayed in the region A32 through a
finger or the like.
[0225] FIG. 22(b) is a diagram showing an example in which the time
zone of a play location of the region A32 has been synchronized
with the time zone of a play location of the region A31.
[0226] As shown, when moving images in different directions are
played at the same time, the controller 180 can synchronize the
moving images on the basis of an image in any one direction.
[0227] FIG. 23 is a diagram showing an example in which when moving
images in different directions are played at the same time, the
moving images are synchronized on the basis of a play location of a
moving image in any one direction.
[0228] As shown in FIG. 23(a), the controller 180 can play moving
images having different time zones in a region A33 and a region
A34, respectively, at the same time. The controller 180 can make a
play location of the region A33 identical with a play location of
the region A34 in response to a signal, such as a drag & drop,
from the region A33 to the region A34 through a finger F10 or the
like.
[0229] In another embodiment, the controller 180 can make a play
location of the region A34 identical with a play location of the
region A33 in response to a signal, such as a drag & drop, from
the region A34 to the region A33 through a finger or the like.
[0230] When moving images having different time zones are played in
respective partitioned regions, the controller 180 can synchronize
the time zones of the moving images in response to a signal, such
as a drag & drop, form one region to the other region.
[0231] FIG. 24 is a diagram showing an example in which an image is
displayed while moving the image on the display 151.
[0232] As shown in FIG. 24, the controller 180 can move a portion
of a 360-degree rectangular image that is being displayed on the
display 151. That is, the controller 180 can move an image I9 left
and right in response to a signal, such as a touch & drag for
the image I9, through a finger F11 or the like.
[0233] As the image I9 being displayed on the display 151 is
moving, the controller 180 can generate signals, such as vibration
and sound S1, so that a user can recognize the moving image at
specific angles r1, r2, r3, and r4.
[0234] A user can intuitively recognize the moving range of the
image through the signals, such as vibration and sound S1, while
moving the image.
[0235] FIG. 25 is a diagram showing an example of the display 151
in which one region of an image is enlarged and displayed.
[0236] The controller 180 can edit and display at least some region
of a rectangular image using one of enlargement edition, reduction
edition, and partition edition methods so that the at least some
region corresponds to a display region of the display 151.
[0237] The controller 180 can edit at least part of a rectangular
image on the basis of a predetermined criterion or in response to a
specific selection signal. That is, the controller 180 can
automatically edit at least part of a rectangular image on the
basis of a predetermined criterion or can manually edit at least
part of a rectangular image in response to a specific selection
signal.
[0238] For example, the controller 180 can adjust the size of an
image based on at least one of the length and breadth of a display
region of the display 151 and display an adjusted image on the
display 151. The controller 180 can adjust the size of an image in
response to a specific selection signal, such as a touch, a touch
& drag, or a tap to the display 151, and display at least part
of the image on the display 151.
[0239] As shown in FIG. 25(a), the controller 180 can display an
omnidirectional image A37 and an image A36 in a specific direction,
that is, a partial region of the omnidirectional image A37, on the
display 151. The controller 180 can display a region, corresponding
to a portion of the omnidirectional image A37 that is being
displayed in the region A36, in the form of a dotted box C1.
[0240] As shown in FIG. 25(b), the controller 180 can enlarge a
selected portion of the omnidirectional image A37 in response to a
selection signal, such as a touch to the selected portion, through
a finger F12 or the like and display the enlarged portion in the
region A36.
[0241] That is, a user can select a region to be selected and
viewed. For example, the controller 180 can enlarge an image C2
including a person 30 in response to a selection signal for the
image C2 and display the enlarged image C2 in the region A36.
[0242] FIGS. 26 to 28 are diagrams showing an example in which one
region of an image is edited, displayed, and stored.
[0243] As shown in FIG. 26, the controller 180 can select one
region of an omnidirectional image and store the selected region.
For example, the controller 180 can store only one region C3 of an
omnidirectional image, displayed in a region A39, in response to a
signal, such as a long touch to the region C3 through a finger F13
or the like.
[0244] As shown in FIG. 27, the controller 180 can select and edit
one region of an omnidirectional image and store the edited
region.
[0245] For example, as shown in FIG. 27(a), the controller 180 can
receive a signal, such as a touch to a region C4, that is, one
region of an omnidirectional image A42, through a finger F14 or the
like.
[0246] As shown in FIG. 27(b), the controller 180 can store only an
image Z1 corresponding to some region C4 of the omnidirectional
image A42 in response to a signal that adjusts the size of the
omnidirectional image A42 through a finger F15 or the like.
[0247] That is, the controller 180 can store only a desired region
of the entire image through processes, such as selection,
enlargement, and reduction for the entire image.
[0248] As shown in FIG. 28, the controller 180 can cut only one
region of an omnidirectional image and store the cut region. For
example, as shown in FIG. 28(a), the controller 180 can cut only a
region Z2 of an omnidirectional image in response to a signal
generated by a touch to the region Z2 through a finger F16 or the
like and store the cut region Z2. That is, the controller 180 can
select one region of the entire image displayed in a region A44 and
store the selected region.
[0249] The controller 180 can display a selected region of the
entire image displayed in the region A44 in the form of a dotted
line or the like so that a user can check the selected region when
performing next edition.
[0250] As shown in FIG. 28(b), the controller 180 can obtain and
store a message n1. That is, the mobile terminal 100 can generate,
edit, and store images having various types of styles by applying
an edition and memo functions to the images.
[0251] FIGS. 29 and 30 are diagrams showing an example in which a
plurality of partitioned images is displayed.
[0252] As shown in FIG. 29, an omnidirectional rectangular image
can be partitioned into various ratios. For example, as shown in
FIG. 29(a), the controller 180 can split an image two partitions
A45, four partitions A46 and so on. Furthermore, the controller 180
can split an image in a specific ratio (e.g., a length:breadth
ratio 3:2, 4:3 or 16:9) on the basis of a portion where a person is
placed.
[0253] The controller 180 can receive a selection signal for
2-partitioned images A45 through a signal, such as a touch, through
a finger F17 or the like.
[0254] As shown in FIG. 29(b), the controller 180 can display the
2-partitioned images A45 in the regions A48 and A49 of the display
151, respectively. The controller 180 can store the 2-partitioned
images. The 2-partitioned images can be results of a 360-degree
image split into two on the basis of 180 degrees of the 360-degree
image.
[0255] FIG. 30 is a diagram showing an example in which the
controller 180 displays images partitioned in various ratios in a
region A50 and edits the images.
[0256] As shown in FIG. 30(a), the controller 180 can partition an
omnidirectional image into two partitions or 4 partitions. That is,
the controller 180 can display partitioned images, such as two
partitions e1 and e2 and four partitions e3 to e6, in the region
A50. The controller 180 can select any one of the partitioned
images e1, e2, and e3 to e6, in response to a signal, such as a
touch & drag through a finger F18 or the like. For example, the
controller 180 may select the partitioned image e1 and move the
selected image e1 to a region A51 in response to a signal, such as
a touch & drag.
[0257] As shown in FIG. 30(b), the controller 180 can select the
partitioned image e6 in response to a signal, such as a touch &
drag, through a finger F19 or the like. That is, the controller 180
can move the selected image e6 to the region A51 in response to a
signal, such as a touch & drag.
[0258] The controller 180 can partition an omnidirectional image
into images in various ratios and collect and combines some of the
partitioned images. For example, the controller 180 can combine the
image e1 and the mage e6.
[0259] FIGS. 31 and 32 are diagrams showing an example in which an
image is edited based on objects included in the image and an
edited image is displayed.
[0260] As shown, the controller 180 may delete only a specific
object included in an image or may select only some objects and
combine the selected objects.
[0261] As shown in FIG. 31(a), a person 33 may be included in an
image. The controller 180 can delete only the person 33 in response
to a selection signal, such as a long touch to the person 33
through a finger F20 or the like.
[0262] As shown in FIG. 31(b), portions t11 and t12 can be arranged
in parallel in the image in the state in which only the person 33
has been deleted.
[0263] If a user wants to capture a 360-degree image using the
mobile terminal 100, the user may want to photograph a scene other
than its own self-shot region. In this case, the controller 180 can
delete and edit only the self-shot portion.
[0264] As shown in FIG. 32, the controller 180 can collect only
specific objects 35 and 36 included in an image and edit the
collected objects 35 and 36. That is, as shown in FIG. 32(a), the
controller 180 can select the objects 35 and 36 in response to
signals, such as long touches to the objects 35 and 36 through
respective fingers F21 and F22 or the like.
[0265] As shown in FIG. 32(b), the controller 180 can combine the
objects 35 and 36 into one image and store the one image.
[0266] FIG. 33 is a diagram showing an example in which the length
and breadth width of an image is adjusted in a specific ratio.
[0267] As shown in FIG. 33, the controller 180 can edit an image in
a variety of length and breadth ratios. For example, the controller
180 can edit an image in a variety of ratios, such as a printing
photograph ratio q1 having a length and breadth ratio of 3:2, a
digital camera photograph ratio q2 having a length and breadth
ratio of 4:3, and a wide image ratio q3 having a length and breadth
ratio of 16:9 ratio. The controller 180 can edit an image in
various ratios in response to a signal, such as a touch through a
finger F23 or the like.
[0268] The controller 180 can store only an image part cut in a
selected ratio as one image file.
[0269] FIGS. 34 and 35 are diagrams showing an example in which
objects included in an image are separated from the image and
displayed.
[0270] As shown in FIG. 34, a plurality of objects can be included
in an image. The controller 180 can separate the plurality of
objects from the image and display the separated objects on the
display 151.
[0271] For example, if a scene in which several persons are having
a conference in a conference room is sought to be captured by the
omnidirectional camera in the form of a moving image, the
controller 180 can edit the captured moving image for each object,
that is, for each person. That is, the controller 180 can separate
images, including respective objects P1, P2, P3, P4, and P5, from
the entire image and store the separate images.
[0272] The controller 180 can play only a desired object image,
from among the object images P1 to P5. For example, the controller
180 can play only the object image P2 in response to a signal, such
as a touch to the object image P2 through a finger F24 or the
like.
[0273] The controller 180 can display all the moving images in one
region A60 of the display 151. The controller 180 can display
moving images, separated for each object, in the other region A61
of the display 151.
[0274] FIG. 35 is a diagram showing an example in which edition is
performed based on a moving object included in an image when the
object moves.
[0275] As shown in FIG. 35, the controller 180 can display all
moving images in one region A62 of the display 151. If an object,
that is, a person 38, included in the one region A62 moves, the
controller 180 can display a screen edited based on the person 38
in the other region A63 of the display 151.
[0276] FIG. 36 is a plan view showing the structure of the
omnidirectional camera 200.
[0277] As shown in FIG. 36(a), the omnidirectional camera 200 in
accordance with an embodiment of the present invention can be
provided on one side of the mobile terminal. FIG. 36(b) is a plan
view of the mobile terminal 100 and is an exploded cross-sectional
view of a portion of the omnidirectional camera 200.
[0278] The omnidirectional camera 200 can include a combination of
a convex lens (201) portion and a concave lens (202) portion. An
opaque cover 203 can be disposed at the upper part of the concave
lens (201) part at the center of the omnidirectional camera
200.
[0279] Since the small-sized omnidirectional camera 200 is embedded
in the mobile terminal 100, inconvenience due to the attachment and
detachment of an additional omnidirectional camera can be
avoided.
[0280] FIGS. 37 and 38 are diagrams showing the structure of a
camera in accordance with another embodiment of the present
invention.
[0281] As shown in FIG. 37, in another embodiment of the present
invention, one camera module 220 can perform both the functions of
an omnidirectional camera and a one-directional camera. That is,
when a lens 212 is covered by lifting a cover 214 up, the camera
module 220 can operate through an interaction with a lens 210
placed at the upper part of the mobile terminal 100. That is, the
camera module 220 can operate as an omnidirectional camera.
[0282] When the cover 214 is lifted down and thus the lens 212 is
not covered, the camera module 220 can operate through an
interaction with the lens 212 placed in the rear of the mobile
terminal 100. That is, the camera module 220 can operate as a
camera for performing one-directional photographing.
[0283] As shown in FIG. 38, in yet another embodiment of the
present invention, the mobile terminal 100 can include two cameras.
That is, an image having high-picture quality can be obtained by
overlapping images 130 and 131 captured by respective
omnidirectional cameras 250 and 251.
[0284] The mobile terminal and the method of controlling the same
in accordance with the present invention have the following
advantages.
[0285] In accordance with the present invention, an omnidirectional
still or moving image can be captured by the omnidirectional camera
embedded in the mobile terminal, and an interface that can be
conveniently used by a user can be implemented.
[0286] Furthermore, in accordance with the present invention, a
ring-shaped image captured by the omnidirectional camera can be
converted into a rectangular image and displayed on the
display.
[0287] Furthermore, in accordance with the present invention, an
object(s) included in an image can be separated from the entire
image and displayed.
[0288] Furthermore, in accordance with the present invention,
images edited for each object included in the entire image can be
displayed at the same time.
[0289] The above-described method of controlling the mobile
terminal may be written as computer programs and may be implemented
in digital microprocessors that execute the programs using a
computer-readable recording medium. The method of controlling the
mobile terminal may be executed through software. The software may
include code segments that perform required tasks. Programs or code
segments may also be stored in a processor-readable medium or may
be transmitted according to a computer data signal combined with a
carrier through a transmission medium or communication network.
[0290] The computer-readable recording medium may be any data
storage device that can store data readable by a computer system.
Examples of the computer-readable recording medium may include
read-only memory (ROM), random-access memory (RAM), CD-ROMs,
DVD.+-.ROM, DVD-RAM, magnetic tapes, floppy disks, and optical data
storage devices. The computer-readable recording medium may also be
distributed over computer systems coupled over a network so that
computer-readable codes are stored and executed in a distribution
fashion.
[0291] The mobile terminal may include a first touch screen
configured to display a first object, a second touch screen
configured to display a second object, and a controller configured
to receive a first touch input applied to the first object and to
link the first object to a function corresponding to the second
object when receiving a second touch input applied to the second
object while the first touch input is maintained.
[0292] A method of controlling the mobile terminal may include
displaying a first object on the first touch screen, displaying a
second object on the second touch screen, receiving a first touch
input applied to the first object, and linking the first object to
a function corresponding to the second object when a second touch
input applied to the second object is received while the first
touch input is maintained.
[0293] Any reference in this specification to "one embodiment," "an
embodiment," "example embodiment," etc., means that a particular
feature, structure, or characteristic described in connection with
the embodiment is included in at least one embodiment of the
invention. The appearances of such phrases in various places in the
